Integrating spheres are relatively new to us, but they are indispensable. What exactly is the role of the integrating sphere?1. What is the integrating sphereThe integrating sphere is a cavity sphere with an inner wall coated with white diffuse reflective material, also known as the photometric sphere, optical flux sphere, etc.. The inner wall of the ball is coated with the ideal diffuse reflective material, also * is the diffuse reflection coefficient close to 1 material. Commonly used material

The working principle of holographic flat-field concave diffraction grating is as follows: the measured light source is projected onto the holographic flat-field concave diffraction grating through the optical filter fiber, and then reflected to the high-precision array detector, with **optimal extinction material to achieve **optimal testing effect. Wisepoint's spectrometer adopts **advanced holographic flat field concave diffraction grating and high performance linear array detector with elect

Polar coordinates: set the center of the graph as point 0, called the polar point, and draw a ray 0X from the polar point, called the polar axis, and then select a unit of length and the positive direction of the angle (usually take the counterclockwise direction). Take a point M on the graph, use ρ to denote the length of the line 0M, θ to denote the angle from 0X to 0M, ρ is called the polar diameter of the point M, θ is called the polar angle of the point M, the ordered number pair (ρ,θ)* is

1. color temperature of a light source is determined by comparing its color with the theoretical thermal blackbody radiator (referred to as a blackbody, an object with an absorption rate equal to 1 for any wavelength of radiant energy at any temperature, an ideal model, also called a complete radiator). The spectrum emitted by a thermal radiation source is continuous and smooth, and for black bodies, the color is * different for different temperatures. There is a unique correspondence between th

As we are familiar with the laptop backlight, it is a combination of many LED beads, and the problem of color difference is becoming more and more obvious. If the use of LED beads is not the same batch, it is easy to lead to different wavelengths, color differences and other problems, this problem is inevitable even if the use of the same batch of LED beads. For the testing of LED chips, the integrating sphere test system is generally used. The use of integrating spheres to measure parameters s
